BACKGROUND: The aim of this study is to define the cardioprotective effects (functional and metabolic) of newly developed DelNido cardioplegic solution (containing plasma solution, mannitol, magnesium and lidocaine). MATERIAL AND METHOD: This study assessed the function of rat hearts after itermittent infusion of DelNido cardioplegia with different preserving methods(Air or Icebox) for 2hours and perfusing the hearts on a Langendorff apparatus. Heart rate, left ventricular developed pressure (LVDP) and coronary flow, were measured at pre-ischemic, post-reperfusion 15min, 30min and 45min. Coronary flow was standardized to dry heart weight. Each weight was weighted to calculate water content. Creatine kinase-MB isoenzyme release was measured and ultrastructural assessment was done with electron microscopes. DelNido group was better than St, Thomas group and Icebox group was better than Room-air group. CONCLUSION: DelNido cardioplegia have better myocardial protective effects than St. Thomas cardioplegia when they were preserved in the Room-air. But we can not tell the difference between Delnido cardiplegia with Air preserving method and St. Thomas cardioplegia with Icebox.

Emphysematous cholecystitis is an uncommon condition which may mimic acute cholecystitis. But it differs from acute cholecystitis in its relatively greater frequency in men and diabetics and has graver prognosis. The condition is diagnosed by demonstration of air in lumen,wall of gallbladder and/or pericholecystic space using a variety of radiographic techniques: simple abdominal radiography, ultrasonography and CT scanning. One illustrative case is presented herein and the pertinent literature is reviewed.

7.Pulmonary Air Leak in the Neonatal Respiratory Distress Syndrome.
The Korean Journal of Thoracic and Cardiovascular Surgery 1999;32(1):38-42
BACKGROUND: In neonatal respiratory distress syndrome patients, various types of pulmonary air leak contributes to elevate morbity and mortality. Although early surgical interventions can provide better results in several cases, whole clinical outcomes are poor. This study was designed to investigate the clinical aspects of pulmonary air leak in the neonatal respiratory distress syndrome patients and major contributing factors to mortality. MATERIAL AND METHOD: We retrospectively evaluated 48 cases of pulmonary air leak in the neonatal respiratory distress syndrome patients from September 1994 to May 1997. RESULT: There were 15 cases of primary and 33 cases of secondary pulmonary air leakages. The prominent manifestations were pure interstitial emphysema in 19 cases(39.9%) and combined pneumothorax in 19 cases(39.9%). In clinical aspects, normal birth weight was dominant(83.4%), the onset occurred within 24 hours was in 28 cases(58.8%). The pulmonary diseases were meconium aspiration syndrome(25.2%) and hyaline membrane disease(33.2%). The overall hospital mortality was 25.2%, and the majority were hyaline membrane diseases. CONCLUSION: Although the overral mortality rate of these diseases were high, more detailed studies about immediate treatement, perinatal prevention, intensive care to geriatric problems were needed individually to improve outcomes.

Schwannomas are benign nerve sheath tumors that can originate at any anatomic sites. These tumors are usually soitary, benign, and slow-growing masses attached to large nerve trunks. These tumors have been described as arising in the pelvic retroperitoneum. We present two cases of pelvic retroperitoneal Schwannomas with a brief review of literatures.

BACKGROUND: Survival time of patients with multiple myeloma has been reported to be closely related to the cytology of bone marrow smears and the histologic features of bone marrow biopsies. However, there have been many differences in morphological criteria applied by various authors. In this study, we evaluated the prognostic relevance of bone marrow features in patients with multple myeloma by investigation of the cytologic feature and the histologic patterns. MATERIALS AND METHODS: One hundred and seven previously untreated patients with multiple myeloma, admitted to Asan Medical Center, between 1989 and 1997, were studied. Bone marrow aspirations and biopsies were analyzed according to the criteria such as cytologic differentiation, volume of infiltration, pattern of infiltration, degree of hematopoiesis, and presence of fibrosis. RESULTS: 64 cases (59.8%) of 107 patients with multiple myeloma were plasmacytic type and 43 cases (40.2%) were plasmablastic type. Each median survival time was 35.0 months and 18.0 months (P<0.05). The patients with more than 25% of plasmablasts showed shorter median survival time than those with 1ess than 25% (18 months vs 38.9 months, P<0.05). The patients with nodular or packed marrow pattern revealed poorer prognosis than those with interstitial or interstitial/nodular pattern (P<0.05). The patients of plasmablastic type disclosed larger volume of myeloma cell infiltration and more packed marow pattern than those of plasmacytic type. CONCLUSIONS: The cytologic differentiation, the volume of infiltration and the patterns of infiltration were reliable predictors of survival in myeloma patients. Thus, for the prognostic evaluation and therapeutic plans, the descriptions for cytologic differentiation (especially percentage of plasmablasts), volume of infiltration and pattern of infiltration should be included in the bone marrow interpretation of multiple myeloma.

Purpose:
: Interviews between the coordinator and the family of the brain dead for organ and tissue donation have a great impact on the increase in the consent rate of organ donation. It is necessary to find out empirically the factors for building a mutually respectful and reciprocal relationship in the interview between the coordinator and the family from the perspective of the research subject.
Methods:
: This study is a qualitative study, and data were collected through in-depth interviews with 10 coordinators of the Korea Organ Donation Agency. The collected data were analyzed by two steps of text analysis and meaning reconstruction.
Results:
: The relationship building factors between the coordinator and the family of the brain dead analyzed in this study include ‘establishing trust, helping the family, empathy, active listening, friendliness, non-burdening, cautious approach, and sincerity’. Coordinators conducted interviews to deliver information to the family of the brain dead, sincerely and carefully through sympathy and listening, while working for the family at the same time. In these interviews, non-verbal and quasi-verbal communication as well as verbal expressions was actively used.
Conclusion
: The results of this study can be used for communication training of organ procurement coordinators.
